Answer / Explanation:
B
Potential difference is measured using a device called a voltmeter . Just like ammeters, some types have a pointer on a dial, but most have a digital display. However, unlike an ammeter, you must connect the voltmeter in parallel to measure the potential difference across a component in a circuit.
Answer:
Reduce you're speed, and let the other vehicle pass you
Hi pupil here's your answer ::
_______________________________
Newton's Second Law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force.
ie., F=ma
Where F is the force applied, m is the mass of the body, and a, the acceleration produced.
Or in simplest language it is the force applied to a particular object of particular mass multiplied by the acceleration caused by force .

Answer:
Resistance to electrical currents
Explanation:
Conductors have low resistance to electrical currents, and are used to "conduct" the flow of electricity.
Insulators have very high resistance and are used to protect us from the flow of electricity.
Answer:
The average force exerted on the window due to two snowballs is 6 N
Explanation:
Given:
Mass of snowballs 
Kg
Velocity of snowball 
For finding the average force,
Force is equal to the change in momentum,
Here, final velocity is zero so we write,
Where 
sec
N
Above value of force is due to one ball, but here given in question there are two ball,
N
Therefore, the average force exerted on the window due to two snowballs is 6 N
